The submarine line for optical-fibres telecommunications, comprises two optical-fibres cables (1, 2), and an optoelectronic repeater (3), interposed between them. …<??>The optoelectronic repeater (3) has its component parts encased in a watertight casing (4) that, in this turn, is enclosed in a metallic-box (13) - whose bases are provided with apertures, facing towards the cables. …<??>The apertures of the metallic-box (13) are sealingly closed by cylindrical bodies (22) - by means of which there is realized both, the mechanical connection - between the box (13) and the armouring of each cable (1, 2) formed by a rope (34) embedded in it, as well as the connection - between the optical-fibres (37) and the conductors of the cables, and the extremities of the optical-fibres (5) and of the electrical-conductor (6) of the optoelectronic repeater (3). |
